Where is the thesis statement located in a position paper

In the Introduction passages to the paper.

Explanation:

A position paper is one i which the researcher argues for a specific position throughout the essay by presenting his evidence and countering previous claims.

This is why, the thesis statement must come at the beginning of the paper, usually after a paragraph or two introducing other ideas that the position of the author is in support  with or disagrees with, so that the rest of the paper can be about the argument.

the correct answer is the first option "the bolkshevik revolution". the passage makes reference to many of important events that occured in the revolution, such as the assemblies, in this case the animals are gathered in an assembly after a protest, the murder of fellow partners, the speeches given by the leader of the revolution, among other aspects. the last choice is possible, but in this passage in particular it is not emphasized the fight between the characters, that is the two pigs, that represent lenin and stallin.
